Design and Analysis of Heat Regeneration Technique in Combined Cycle Power Plant

In recent years, energy efficiency becomes one of the most frequently discussed topics in international forums and community, from which the notion of optimizing energy resources is introduced. Heat regeneration represents a mechanism to reuse the heat energy which is wasted during the energy conversion process, such practice is also known as combined cycle technique. This paper presents the analysis of a conversion from open cycle gas turbine power plant into a combined cycle power plant based on mathematical modeling and simulation. The scope is limited to the study of heat regeneration process in Heat Recovery Steam Generator (HRSG), during which the running process converts feed water into steam before it is fed into a steam turbine to generate electricity. The main concerns to be examined involve the mechanical analysis of heat transfer media and PI controller design of heat exchanger.
